"This greenhouse hasn’t just given me a new way to grow; it’s become the centerpiece of my entire homestead. It’s the one place where I genuinely want to spend every waking moment!" Salty Dawg Homestead

Does it ship freight?
No. It ships free in standard boxes to your door.
How long does it take to build?
Most builds take one to two days with two people on a prepared site. One person can build it with extra time. Optional upgrades like doors and roll-up sides may add time.
Can a beginner do this?
Yes. The instructions and video guide break each step down clearly. Our USA based support team is available seven days a week if you need help during assembly.
What ground prep is needed?
Choose a level area with good drainage. Clear debris, remove rocks or roots, and make sure the ground is firm. Gravel or compacted soil work well.
Is this strong enough for year-round use?
Yes. With proper anchoring and seasonal care, the greenhouse is suited for ongoing use. In areas with heavy snow or strong winds, additional anchoring or periodic snow removal may be needed.
Grew these for the past three years and I will keep growing them for many more. I highly recommend them. Great germination rate. Every onion grew to the size of baseballs and others a bit bigger and they store very well.Best long day onion I have ever grow.
I am very happy with my heirloom seeds. I cannot wait to germinate them.
Started my seeds on 12/31/25. I’ve had almost 100% germination and the onion seedlings are a couple of inches tall at this point (1/9/26). Looking forward to a great harvest!
Grew these last year, so I bought more seeds! they were awesome, very prolific and tasted great!!
I started them early....did waterjug winter seed starts .. they did very well....grew up to be nice sturdy plants, bearing lots of fruit! Thank You!!
